CustodySplit Privacy Policy
CustodySplit holds information about your family, including your children. This policy says exactly what we collect, why, who else sees it, and how to delete it.
Last updated:
Who this policy is from and what it covers
This Privacy Policy explains what information Isaac Grey - Developer (“we”, “us”) collects when you use CustodySplit, why we collect it, and what you can do about it. It covers the CustodySplit mobile app on iOS and Android, and this website.
CustodySplit is a scheduling tool for separated and divorced co-parents. The information you put into it is about your family and your children, which is why this policy is specific about where that information goes rather than reserving the right to do anything with it. We do not sell personal information, we do not run advertising, and we never use information about a child for marketing.
Using the app is also subject to our Terms of Service.
What information we collect
Grouped below by the same categories the App Store and Google Play use on their privacy labels, so what you read here matches what you see on the store listing.
Account information
Your email address, and the sign-in identifiers our authentication provider creates for your account. We do not store your password — the authentication provider handles it.
Content you create in the app
This is the bulk of what we hold. It includes:
- Your custody schedule and its rotation pattern.
- Calendar entries, exchange days, holidays, swaps, and one-off changes.
- Information about your children that you choose to enter, such as a first name or nickname and dates that matter to the schedule. Only what you type in — the app does not ask for a child’s birth certificate, school, address, or any government identifier.
- The free-text description you type in the setup chat when you tell the app how you share time. See how the setup chat works.
Purchase information
Whether your subscription is active, when the trial started, and which plan you are on. Payment is taken by Apple or Google, not by us: we never receive your card number, bank details, or billing address. What reaches us is a purchase identifier and a subscription status.
Device and diagnostic information
When the app crashes, it sends a diagnostic report to Sentry containing the error, the device model, and the operating system version, so we can find the fault. The app does not include an advertising or product-analytics SDK and does not collect an advertising identifier.
This website’s host records standard server request logs (IP address, browser type, page requested) as part of serving pages.
What we do not collect
Stated plainly, because for an app like this the absences matter as much as the collections. CustodySplit does not collect:
- Precise or background location. The app never requests GPS.
- Your contacts or address book.
- Your photos or camera.
- Health information.
- Payment card numbers or financial account details, as described above.
Information about children
CustodySplit is a tool for adults. It is intended for parents and legal guardians aged 18 or over, it is not directed at children, and children do not have accounts. We do not knowingly collect personal information from a child under 13. If we learn that a child under 13 has created an account, we delete it and its data.
A parent using the app does, however, enter information about their children — a name, and dates tied to the schedule. We treat that information as follows, and these are commitments, not preferences:
- It is used only to build and display your custody schedule.
- It is never used for advertising, marketing, or profiling — not for you and not for your child.
- It is never sold, and never shared with a data broker.
- It is shared only with the service providers listed in third-party service providers, who process it on our instructions to run the service, and with a linked co-parent as described in what your co-parent can see.
- It is deleted when you delete your account. See how to delete your account and data.
You control how much you enter. A first name or an initial is enough for the app to work; nothing requires you to identify your child more precisely than that.
How we use your information
We use the information above to:
- Create your account and sign you in.
- Turn the description you type in the setup chat into a custody schedule.
- Store, display, and sync your calendar, including to a linked co-parent.
- Start and manage your trial and subscription.
- Answer your support requests.
- Send you service messages — a password reset, a change to this policy, a notice that a trial is ending. These are not marketing and you cannot be opted out of the ones required to operate your account.
- Diagnose crashes and fix bugs.
- Meet legal obligations and enforce our Terms of Service.
To state the boundaries affirmatively:
- We do not sell your personal information, and we do not share it for cross-context behavioural advertising as those terms are defined under California law.
- We do not show third-party advertising in the app and do not provide your information to advertising networks.
- We do not use information about your children for any marketing purpose.
- We do not use the contents of your calendar to build a profile of you for anything other than running the service.
How the AI setup chat works
When you set up CustodySplit, you describe your custody arrangement in your own words — for example “we do 2-2-3, and we alternate Christmas”. That text is sent to Anthropic, an artificial intelligence provider, which interprets it and returns a schedule pattern. That is the only way the app can build your calendar from a sentence instead of a form.
What this means in practice: whatever you type into the setup chat leaves our systems and is processed by that provider. If you include a child’s name in your description, that name is included. You can describe your arrangement without naming anyone — “the kids” works as well as a name — and we suggest doing so if you would rather it not be sent.
Third-party service providers
We use the companies below to run CustodySplit. Each one receives only what it needs for its stated purpose, processes it on our instructions, and is not permitted to use it for its own marketing. None of them is a data broker and none receives your information for sale. Each provider’s name links to its own privacy policy.
| Provider | What they do for us |
|---|---|
| Supabase | Hosts the database and runs account sign-in. Stores your account, schedules, and calendar entries. |
| Anthropic | Turns the description you type in the setup chat into a custody schedule. |
| RevenueCat | Tracks whether your subscription is active. Receives a purchase identifier, not your payment details. |
| Apple | Distributes the iOS app and processes payment for subscriptions bought on iPhone or iPad. |
| Distributes the Android app and processes payment for subscriptions bought through Google Play. | |
| Sentry | Receives a diagnostic report when the app crashes, so we can find and fix the fault. |
| Vercel | Hosts this website. Receives standard web server request logs. It does not host the app's data. |
We may also disclose information if the law requires it — a valid subpoena, court order, or legal process — or where we reasonably need to in order to protect someone’s safety or our legal rights. If our business is sold or merged, your information may transfer to the acquirer, who would remain bound by this policy until you are told otherwise.
What your co-parent can see
CustodySplit is a shared calendar. That is the product: when two parents look at the same schedule, there is less to disagree about. It also means that once your account is linked to your co-parent’s, they can see the schedule information the two of you share.
What is not shared with your co-parent: your password, your subscription and billing status, and your support correspondence with us.
Please treat anything you enter as visible to the other parent, and decide accordingly. If you need to end a link between accounts, or if you have a safety concern about a linked account, contact us at freelancer5323@gmail.com.
How long we keep your information
We keep your account and calendar for as long as your account exists, because the whole point is that your schedule is there when you open the app. When you delete your account, we delete that data from our live systems.
- Backups: deleted records can persist in encrypted backups for a limited period before those backups roll over. Retention window: 30 Days.
- Inactive accounts: Inactive accounts are not removed.
- Purchase records: we keep a record of transactions for as long as tax and accounting rules require, separately from your calendar.
- Support messages: Support messages are stored indefinitely.
How to delete your account and your data
You can delete your CustodySplit account and the data in it at any time. You do not need to contact us first, and you do not need an active subscription to do it.
Deleting from inside the app
- Open the CustodySplit app on your iPhone or Android phone and sign in.
- Go to Settings → Delete Account.
- Confirm when the app asks you to.
Deleting by email
If you cannot sign in, email freelancer5323@gmail.com from the address on your account and ask us to delete it. We will verify that the request comes from the account holder before acting on it, and we will confirm when it is done.
What gets deleted
Your account and sign-in identifiers, your custody schedule and every calendar entry in it, any information about your children that you entered, and the text you typed in the setup chat. Deletion is permanent — we cannot restore a deleted account, so export or note anything you still need first.
What is kept, and for how long
Deleted records can remain in encrypted backups for 30 Days before those backups roll over. We also keep transaction records where tax and accounting rules require it. Neither is used for any other purpose.
Two things deletion does not do
- It does not cancel your subscription. Subscriptions are billed by Apple or Google and must be cancelled in the App Store or Google Play subscription settings. Cancel there first, or you may continue to be charged.
- It does not delete your co-parent’s account. They hold their own account, with their own copy of the shared schedule, and only they can delete it.
How we protect your information
Data is encrypted in transit between the app and our servers using TLS, and encrypted at rest by our hosting provider. Access to production data is restricted to the people who need it to operate the service. Database access rules are configured so that an account can reach its own records and its linked co-parent’s shared records, and not other users’ data.
No service can promise perfect security, and we will not pretend otherwise. What we can tell you is that we will notify affected users without undue delay if a breach affects their personal information, and as required by law.
You have a part in this too: use a password you have not used elsewhere, and tell us at freelancer5323@gmail.com if you think someone has your account.
Your privacy rights
Whoever you are and wherever you live, you can ask us to show you your data, correct it, or delete it. Email freelancer5323@gmail.com, or use the in-app steps in how to delete your account and your data. We will verify that the request comes from you before we act on it, which normally means replying from the email address on the account.
If you live in California
The California Consumer Privacy Act, as amended by the CPRA, gives you the right to:
- Know what personal information we collect, why, and who we disclose it to — set out in what information we collect and third-party service providers.
- Access a copy of the personal information we hold about you.
- Correct inaccurate personal information.
- Delete your personal information, subject to the narrow exceptions the law allows.
- Limit our use of sensitive personal information.
- Not be discriminated against for exercising any of these rights. We will not degrade the service, change your price, or refuse you service because you made a request.
We do not sell personal information and we do not share it for cross-context behavioural advertising as the CPRA defines those terms, and we have not done so in the preceding twelve months — including for consumers we know to be under 16. There is therefore no “Do Not Sell or Share My Personal Information” mechanism to offer you; there is nothing to opt out of.
You may use an authorised agent to make a request on your behalf. We will ask for proof of their authority.
If you live in another US state
Several states have their own consumer privacy laws with similar rights of access, correction, and deletion. If you live in one of them, contact us the same way and we will honour the rights your state gives you.
Where your information is processed
We are based in the United States and your information is stored and processed there, on infrastructure operated by the providers listed in third-party service providers.
CustodySplit is offered to users in the United States. If you use it from elsewhere, you are sending your information to the United States, where privacy law differs from your own country’s. Should we offer the app in the European Economic Area or the United Kingdom, we will update this policy first to set out the legal bases we rely on, your rights under the GDPR or UK GDPR, and the transfer safeguards that apply.
Changes to this policy
We update this policy when the app changes — a new service provider, a new category of information, a new feature that shares something it did not share before. When we do, we change the “Last updated” date at the top of this page.
If a change materially affects how we handle your information, we will tell you before it takes effect, by email or in the app, so you can decide what to do about it. Continuing to use CustodySplit after a change takes effect means you accept the updated policy.
